SPECIFICATION forming part of Letters Patent No. 504,991, datedSeptember 12, 1893.

Application filed May 8, 1893. Serial No. 472,828. (No model.)

To aZZ whom it may concern:

Be it known that I, J AMEs A. MITCHELL, a citizen of the United States,residing at Mart1nsburg,in the county of Berkeley and State of WestVirginia, have invented certain new i and useful Improvements inWire-Fence Machines; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has relation to improvements in machines for making wirefences and it consists in the novel construction and arrangement andcombination of parts all as will be hereinafter more fully described.

. The annexed drawings to which reference is made, fully illustrates myinvention, in which- Figure 1 represents a side view of my device; Fig.2, arear view of the same. Fig. 3 is a transverse section. Fig. 4 is a.perspective view of one'half of a twister. Fig. 5, is a front view of atwister, and Fig. 6 is a perspective view of the central portion of oneof the twisters.

Referring by letter to the accompanying drawings A, A, designate twintraveling bars, which are loosely attached to the frame B, of themachine. These bars are designed to move alternately and in a Verticaldirection up and down, and the same are held to the frame by bands a;the ends thereof having bolts b, which pass thi'ough slots c in thevertically moving bars A, A. These slots c serve the purpose of guidingthe bars A, A, in their Vertical movement; prevent lateral movement andat the same time limit the up and down movement of said bars, forming astop therefor. Each of these bars is provided with a series of plates dadapted to hold the twisters in position on the movable bars. Clearlyshown in Fig. 2 of the drawings. These twisters are constructed withsemicircnlar flanges e and a cut away portion on the face of which is astud g which receives the Wire spool, and a projection h having aperforation 'i through which the Wire passes. These flanges e fit snuglyand work in recesses a' in bars A A corresponding to the contonr of saidfianges and the semicircular portion C02 of the twisters also work inrecesses ota in the edge of thebars A, A. These twisters are 'arrangedin pairs and are composed of two half Sections or twins having betweenthem a central piece j, which has a longitudinal hole k for thehorizontal Wire. These central pieces are constructed with a stem Z,which sterns have their bearing in the frame of the machine, and the endthereof is provided with a gear wheel m, which ineshes with the adjacentgear wheel of the next twister; th us gearing the twisters to oneanother vertically and providing means whereby all the twisters aresimultaneously operated, suitable gear being provided as at n having acrank handle 0 whereby when the same is turned the entire train ofgearing is operated and thus revolving the twisters.

To the upper end of each of the vertically moving bars is pivoted theends p of a rocking bar q, which is centrally pivoted as at r to thecentral portion of a frame s, secured to the top of the frame of themachine and to the side of one of these bars A, is secured a toothedrack bar t which engages a pinion u on a shaft'u journaled at 'w on themain frame.

Said shaft has a crank arm w, whereby when.

the same is operated the Vertically moving bars are caused to travel upand down alternately, through the medium of the rock bar pivoted on topof the frame as aforesaid. The lower end of the main frame is providedwith transporting Wheels y, which support the frame.

In front of the frame is pivoted, as at z, to the frame a', a hand leverb', to the lower end of which is pivoted a bar c'; the free end of whichhas a hook d' ,that engages the rack or teeth in a bar e', thus when themachine is in operation in building a wire fence, as the work progressesthe operator works the hand lever and thus causes the hook to engage theteeth thereby drawing the machine forward. A pawl' is pivoted to therear of the machine and engages the teeth in the bar,-and prevents anybackward movement of the machine.

It will be seen that by my construction of a Wire fence machine that theoperator in moving the machine forward simply grasps the hand lever b'and draws it forward, when the toothed bar engages the teeth in the bare', and draws the machine forward, and in IOO shifting the side wires inWeaving a'fence, the operator simply operates the crank arm x, thusforcing one of the bars A np and the other down simultaneously while thecentral line wire remains stationary.

Asuitable track may be employed on which the frame may travel.

A machine as hercin described is simple in operation, durable and at thesame time cheap to manufacture.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with the main frame, the Vertically sliding bars,slotted and having the plates on their face, of the twister composed ofltwo sections having the flange e, a cutaway portion, spool holder orStud, and flange having the perforation t', all substantially asdescribed.

2. The combination with the main frame, sliding bars, and twisters, andplates for hold- 1ng said twisters in position, of the pivoted rock barattached to the top of the frame, and pivoted at its ends to the top ofeach sliding bar, and the rack secured to the side of the sliding bar A,the pinion therefor, journaled on the edge of the main frame and crankarm m, all substantially as described.

3. The combination with the main frame, sliding bars, twisters, rockbar, pivoted on the top of the main frame, rack t secured to the edge ofthe bar A pinion. and crank arm a: for Operating the same, and thetoothed bar e', of the lever b', pivoted to the frame, the toothed barc' pivoted to this lever and adapted to engage the bar e' having theteeth, and the pawl pivoted to the rear of the frame and engaging saidteeth, all substantially as described.

In testimony Whereof 1 affix my signaturein presence of two witnesses.

JAMES A. MITCHELL.
